Also used data from Gillette (1909), Gillette & Palmer (1932), Palmer (1952) and MacGillivray (1960). Etymology. The name viburnicola derived from the generic name of host-plant “ Viburnum ” and the ending “- cola ” stand for “inhabitant of”. Gender: feminine. Description. Fundatrix. Body broadly elliptical, sometimes almost round, 1.3–2.4 times as long as its width. Bluish white, due to the entire body, except the terminal segment of the abdomen, being covered with a white powder; without powder from light green to deep green; distal half of antennae (including processus terminalis), two last segments of rostrum, tibiae, tarsi, siphunculi, anal and genital plates and cauda dusky to black; distal halves of middle and hind femora dusky. Cleared specimens with basal halves of tibia almost black, two last segments of the antennae (or the apex of third and last segment in 4-segmented antennae), apices of fore femora, distal halves of middle and hind femora, distal halves of tibia, tarsi and siphunculi dark brown, antennae (except for the last two segments), last two segments of rostrum, sclerites and bands on tergites of the abdomen and peritremes, the subgenital and anal plates and cauda brown, head, coxae, trochanters, basal halves of fore and bases of middle and hind femora light brown. Dorsal surface of thorax and abdomen almost not sclerotized, sclerotized only rare small sclerites on abdominal tergites I–VII, band on tergite VIII, small marginal sclerites on segments I–VII and peritremes; sclerites on tergite VII sometimes grouped together in strongly interrupted band. Surface of dorsal side of head smooth, of ventral side of head with sparse pointed spinules; on dorsal side of thorax and abdominal tergites I–VI smooth, on marginal sclerites on abdominal segment VII with rows of large pointed spines; on tergite VII with rows of small pointed spinules which on tergite VIII partially fused and forming short scales; surface of ventral side of thorax smooth, of abdomen with long rows of small pointed spinules sometimes forming strongly stretched cells. Marginal tubercles always present on pro-, meso- and metathorax and on abdominal segments II–IV, tubercles are absent on other body segments; total number of marginal tubercles on whole body—8–12. Spinal tubercles sometimes present on abdominal tergite VII. Setae on the whole body and appendages are finely pointed, except tibia, where some of setae pointed, but not finely pointed. Chaetotaxy of first tarsal segments 3,3,3. Head with weak traces of epicranial coronal suture or without such traces. Antennae 5-segmented or rarely 4-segmented as a result of fusing of 3rd and 4th segments or 3rd, 4th and 5th segments; antennae without secondary rhinaria. Rostrum reaching mesothorax; ultimate rostral segment short wedge-shaped with slightly concave edges. Legs shortened. Spiracles rounded reniform. Peritremes on abdominal sternites I and II separated by a distance more than diameter of peritreme. Siphunculi without setae. Cauda elongated escutcheon-shaped. Hind tibiae not noticeably swollen and with 7–17 pheromone plates on apices. Alatae viviparous female (emigrant). Body egg-shaped, 1.8–2.3 times as long as its width. Head and thorax black, abdomen pale greenish yellow with dusky to blackish green lateral areas and dorsal bands; antennae, legs (except proximal ends of femora), rostrum, siphunculi, and anal and genital plates dusky to black; cauda pale to dusky. Cleared specimens with head, thorax, antennae (except processus terminalis of last antennal segment), distal halves of fore femora, middle and hind femora (except base), bases and apices of tibia (less often the whole tibia), tarsi and siphunculi dark brown; two last segment of rostrum, middle parts of tibiae, sclerites and bands on tergites and sternites of abdomen, marginal sclerites and peritremes on abdominal segments I–VII and subgenital and anal plates brown; processus terminalis, coxae, trochanters, basal halves of fore femora, base of middle and hind femora and cauda light-brown. Abdominal dorsum with sclerotized bands on all tergites and large marginal sclerites on segments I–VII; band on tergite I thin, sometimes divided into large separate sclerites; bands on tergites II–VII and marginal sclerites on segments V–VII fused in a sclerotized shield on which sometimes present a membranous area on the boundary between tergites; band on tergite II fused with sclerotized shield anterolaterally with a membranous area on the boundary between tergites II and III. Ventral side of abdomen with paired sclerotized maculae located along margins of sternites II–VI. Surface of dorsal side of head smooth, of ventral side of head with sparse pointed spinules; on the pronotum with large pointed spines, sometimes sparse, and sometimes located more or less along the contour of the cell; on the mesonotum and metanotum and on the ventral side of the thorax smooth; on abdominal tergites I–VI with large pointed spines, rare on the anterior tergites and more frequent on the posterior ones, where they form a more or less distinct cellular structure; on tergite VII cells begin to disintegrate, spines slightly smoothed out and forming short rows and on tergite VIII spines partially fused and forming short scales; marginal sclerites on tergites I–VII with rows of large pointed spines forming cellular structure; surface of ventral side of abdomen with long rows of small pointed spinules sometimes forming strongly stretched reticulate cells and spinules are expressed more clearly on sclerotized areas. Marginal tubercles always present on prothorax and abdominal segments I–IV; total number of marginal tubercles on whole body—8–10; they protuberant up to semicircular or papilliform, diameter of tubercles 1.1–2.6 times as long as high. Spinal tubercles always present on abdominal tergite VII and very rare also on tergite VI. Setae on the antennae, dorsal side of head, thorax, legs and on abdominal tergites I–V pointed or finely pointed, on abdominal tergites VI–VIII, on ventral side of head and body, rostrum, subgenital and anal plates and cauda finely pointed. Chaetotaxy of first tarsal segments 4,4,4, only rarely on one leg first tarsal segments with 3 or 5 setae. Head with or without weak traces of epicranial coronal suture, frontal tubercles are low, but distinct, median tubercle not reaching the level of antennal tubercles. Antennae 6-segmented and only small part of individual have one 5-segmented antenna as a result of fusing of 3rd and 4th segments; 3rd antennal
